Today is Lady Day whence back in the day this was the New Year Day by the reckoning of certain Western European cultures.
Lady Day celebrates the Feast of the Annunciation because it is exactly nine months before Christmas. Of course, this reckoning is wrought with all sorts of flaws -- like Jesus was born in July -- so maybe that's why the tradition changed. Of course, this day celebrated the Lady long before Jesus camped in the desert. (The Annunciation painted by Henry Tanner.)
